Log a poop by taking a picture of it. Butty, the app's AI, reads the photo and gives you its Bristol type, 1 to 7 on the clinical stool scale, with a short line on what that type means. The log saves with its date and time, so a few seconds in the bathroom builds a history you can read back. YOUR OVERALL POOP HEALTH SCORE Every typed log feeds one number for the last 7 days, drawn on a gauge running 10 to 96. Type 4 is the ideal and both ends of the scale count equally against you, so 1 and 7 score the same. Four colour bands, green through red, and the number moves as your week does. The score is not a diagnosis. WHAT YOU CAN LOG - A photo, typed by AI or picked yourself from the seven Bristol types - Colour - Pain, 0 to 10 - Glasses of water - Straining, urgency, and whether it felt complete - Sleep - A note on what you ate - Medication - Location, if you want it WHAT HOME SHOWS YOU - Butty's read on your week in plain English - Your most recent log - Your poop average: the most common type over 7, 30 or 60 days - Your last three logs, with every log a tap away - Poop distribution: how your types split over 7, 30 or 90 days - A calendar marking every day you logged, the types you had and that day's score - Trends over 30 days for type, how often, pain, water, how it felt, and the days you took medication - Your own map, with a pin on every log you saved with location - A streak count for days in a row - A card flagging a log that needs you, such as a colour worth checking or an analysis that did not finish GUT HUB Everything from Nurse Wong RN BSN, who Butt Talks was built with: - A 1-on-1 video call, booked and paid for in the app - Courses, a short video a day - Her recommended products - The Butt Talks Discord RANKING A leaderboard for the world or your own area, and a community map of everyone logging. One pin marks a whole city, never where anyone actually went. REMINDERS A daily reminder at a time you pick, sent only on the days you have not logged yet. BUTT TALKS PLUS Free accounts get 3 AI checks a week and the last 7 days of history. Plus lifts both: - Unlimited AI checks, so Butty reads every photo you log - Your whole history instead of the last 7 days - Trends, and the 30, 60 and 90 day windows on the average, distribution and calendar cards - Your whole map US$9.99 a month, renewing until you cancel.
